" UNITED STATES EDWARD T. MALONE, OF LACKAWANNA, NEW YORK.

HAND TRUCK.

Application filed April 22, 1922. Serial No. 555,979.

To all whom it may concern:

Be it known that I, EDWARD T. MALONE, a citizen of the United States, residing at La'ckawanna, in the county of Erie and State of New York, have invented certain new and useful Improvements in Hand Trucks;,and I do hereby declare the fol lowing to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This lIU'GIlllOIl relates to hand trucks, and more particularly to hand trucks such as are commonly used for conveying boxes and iMLIIelS.

The object of the present invention is to provide a hand truck of an improved con- ..i-ruction embodying means enabllng it to be used on stairs or simllar structures and also embodying novel features for readily securing the packages upon it.

The invention consists in the novel construction, arrangement and combinations of parts as hereinafter more particularly described and claimed.

Two sheets of drawings accompany this specification as part thereof, in which like reference characters indicate similar parts throughout.

Fig. 7 is a detail fragmentary view taken in section on the line 7-7 of Fig.

in accordance with the present invention,

' 1: frame 1 is provided which is of substan- 'ially rectangular form and preferably made from bar metal or metal tubing. One end 2 of this frame is bent perpendicularly to the main frame to provide a heel. Hangers 5-5 consisting of sheet metal bentsnugly around the sides of frame 1 and having their depending parts welded or otherwise secured together, carry a main axle 3 and a secondary axle 6 above and in spaced relation to the main axle. Upon the main axle 3 are mounted wheels 4 exteriorlyof the frame while within the frame, but adjacent thereto on. either side or elsewhere intermediate the frame parts as may be desired are secured frame guides 7 which may be of U-shaped cross section as here illustrated or other suitable shape as may be desired, and which, as indicated, may be provlded in any number or particular position relative to the frame as may be desired. Further, these frame guide members 7 may be straight and parallel with the side members 1 of the frame or they'may be bent as illustrated in Fig. 5, or otherwise to suit the purposes to which the particular truck is to be applied. These frame guide members 7 are secured upon the shafts 3 and6by having their ends bent up and over these shafts as is illustrated in Fig. 5, and indicatedin Figs. 6 and 7. Upon these frame guides 7 are mounted endless chains 9, formed of a plurality of links 10 united by pins 18 upon which a tread or facing 11 of leather; rubber or other suitable material is supported. Pins 18 are pivoted. adjacent the inner edge of links 10 and are further provided with rollers 19 which are adapted to contact with the face of guide 7 as is well illustrated in Fig. 7.

Sliding upon the side members 1 of the main frame and above the auxiliary axle 6 is a transverse supporting member 12 slidable upon the frame and secured thereto by having its ends bent over and around the frame loosely as at 13. One end is further provided wlth an extending lug 14 bent downwardly as illustrated in Fig. 2, and provided with a slot 15 adapted to receive the links of a chain 16 to secure the same, the other end of the chain 16 being provided with a 'U' stirrup member 17, the legs of which are'adapted to straddle the member 12 and to be bent around the frame member 1 loosely on either side of member 12 ,so that it will be moved upon the frame 1 bymovement of the part 12 simultaneously therewith.

In operation, the barrel or other article to be conveyed is lifted upon the heel 2,

secure the same in position. Upon a level surface the truck operates upon wheels 4 as is customary, but upon ascending or descending stairs the endless chains 9 will come into operation as is well illustrated in Fi re 5.

odifications in the precise details of construction and arranvement of parts will readily suggest themselves to'those skilled in the art, but all within the scope of the present invention.

I claim:

1. In a hand truck having a frame consistingof parallel side members, a transverse axle and supporting wheels mounted on the axle, guide frames supported directly from the axle and the frame and endless tread parts slidably mounted on the guide frame.

2. In a hand truck, a skid device comprising a guide frame extending longitudinally of the truck and directly from the axis of the truck wheels being spaced from and below the frame and an endless tread slid-- ably mounted on said guide frame so as to contact its lower face.

3. In a hand truck, a skid device comprising a guide frame of U-shaped cross section having its ends bent arcuately in the same direction and away from the flanged face to provide pivots and an endless chain tread slidably mounted on said guide between its flanges and extending over its upturned ends, said guide frame bein supported from the1 truck frame through said arcuately bent en s.

4:. A hand truck comprising in combination, a frame having side members, an axle, a supplementary axle, wheels mounted on the axle, skid guide frames extending be: tween the axle and the supplementary axle, endless tread members slidably mounted on the skid guide members, and adjustable securing means for securing the load in position on the truck.

5. In a hand truck'of the class described having parallel side frame members, a transverse supporting member slidable longitudinally on the side frame members, a chain having one end slidably secured to one side frame member in association with the transverse supporting member and means for interlocki'ngthe free end of the chain with the other end of the transverse supporting member comprising an outward-
